PHY242H5S Internal Flow Problems (2) A Venturi meter is a device that is used for measuring the speed of a fluid within a pipe. The drawing shows a gas flowing at speed v 2 through a horizontal section of pipe whose cross-sectional area is 2 2 0.0700 Am = . The gas has a density of 3 1.30 / kg m ρ = . The Venturi meter has a cross- sectional area of 2 1 0.0500 = and has been substituted for a section of the larger pipe. The pressure difference between the two sections is 21 120 P P Pa −= . Find (a) the speed v 2 of the gas in the larger original pipe and (b) the volume flow rate Q of the gas. (3) Water ( 3 1.00 10 . Pa s µ = × ) is flowing through a horizontal pipe with a volume flow rate of 0.014 m 3 /s. As the drawing shows, there are two vertical tubes that project from the pipe. From the data in the drawing, find the radius of the horizontal pipe. Assignment 3 Internal Flow (1) Two hoses are connected to the same outlet using a Y-connector, as the drawing shows. The hoses A and B have the same length, but hose B has the larger radius. Each is open
